1. In a garbage-burning furnace a casing, a horizontal partition therein dividing it into a lower combustion-chamber and an upper drying-chamber, the drying-chamber being provided with a feed-opening at one end and with an opening at the other end providing communication with the combustion-chamber, means for moving the garbage along said partition from the entrance to the exit of the drying chamber, the combustion chamber having an exit for the products of combustion and a main grate, an inclined grate arranged to deliver the garbage to the main grate from the entrance to the combustionchamber, the bars of said grates being hollow and perforated and having a common tubular support at their adjacent ends said support being adapted to supply a gaseous element to the interior of said grate-bars, in combination with means for withdrawing the gases from the drying-chamber and supplying them to said tubular support.
